CAREER: Effective Field Theories from String Compactification

Project: Research project

Description

This CAREER proposal describes an integrated program of research, teaching and outreach, focusing on string theory, quantum field theory, and particle physics. The primary objectives for this project are:

The development of new tools in the study of string compactification at
strong coupling, and the resulting low energy effective field theories. Particular emphasis will be placed on compactifications of F-theory. This will
entail developing the correspondence between the open string degrees of
freedom in the worldvolume theory of intersecting seven-branes, and closed
string degrees of freedom captured by elliptically fibered Calabi-Yau
manifolds.

The development of specific string-motivated scenarios for physics
beyond the Standard Models of particle physics and cosmology. Particle physics applications will include the study of kinetic mixing with a
strongly coupled extra sector. Cosmology applications will include the
development of inflationary reheating scenarios coupled to concrete
stringy particle physics models.

To use the geometry of F-theory compactifications as a tool to
classify and study superconformal field theories (SCFTs) in diverse dimensions. This will include a classification of 6D SCFTs, the construction of new 4D N = 1 SCFTs from D3-brane probes of singular Calabi-Yau fourfold geometries, and the development of 2D SCFTs with N = (0,2) supersymmetry from F-theory and D3-branes in Calabi-Yau fivefold geometries.

To develop an active outreach program in the southeast region
at the postdoc, graduate, undergraduate, high school and middle school levels, and at the broader adult interest level. The PI will work closely with local outreach efforts centered in his department, and with the Morehead Planetarium and Science Center to explain the exciting modern developments in high energy theory and experiment.
